Gov. Andrew Cuomo says Sunday the projects include installing flood barrier berms, concrete floodwalls and gravity drains as well as replacing generators and rehabilitating the airport's power distribution grid.
Cuomo says about 100 million gallons of water flooded the airport during Sandy.
He says flood water in the pump houses rendered them temporarily inoperable. Commercial flight operations were closed for three days. The airport is located between two bays on the East River. He says about $28 million of the costs will be covered by federal disaster recovery funds awarded to the Port Authority of New York and New Jersey.
